Suggestion: add “magnetic edges” to PI structures and extractor heads
Keywords: magnetic edges, user interface, planetary interaction, UI, PI
Note: easier placement of structures and extractor heads
I doubt many of us like seeing the red numbers when extractor heads overlap and so most of us will likely try to move extractor heads close, but not too close, at which point it becomes fiddly.
Giving structures and extractor heads a magnetic edge, which allows them to snap to each other (only needs to be a mild effect of 3-5 pixels), will make their placements much nicer and faster. Also patterns may look a little nicer and not so messy, which makes it more lovely all round.
I’d even go as far as disallowing PI structures to overlap at all, because they cannot actually be placed this way. Yet it’s possible to move them so that they cannot be placed. A simple bounds check would make this also easier to handle.
